Newest solar connected battery facility in Macon-Bibb County adds 128 MW of storage to grid

ATLANTA, Sept. 15, 2026 /PRNewswire/ — Georgia Power leaders recently joined state and local officials and leaders from Robins Air Force Base to celebrate the commercial operation of the Robins Battery Facility, a 128-megawatt (MW) battery energy storage system (BESS) located near Warner Robins, Ga. The facility can deliver stored energy to the grid for up to four hours, enhancing grid reliability and flexibility. Paired with the nearby Robins Solar Facility, the battery system strengthens energy resilience and helps support Georgia’s continued growth.

Robins Air Force Base Col. Johari Hemphill, Sen. Larry Walker, Sen. David Lucas, Sen. Steven McNeel, Rep. Anissa Jones, Central Georgia Joint Development Authority Chairman James Vaughn, Macon-Bibb County Mayor Lester Miller and other community leaders joined Georgia Power executives to celebrate the commercial operation of the Robins Battery Facility. The event reflected the strong partnerships that helped bring the project to life and highlighted its role in strengthening Georgia’s energy infrastructure while supporting economic growth and investment in Macon-Bibb County.

“Seeing the Robins Battery Facility enter commercial operation is an important milestone for Georgia Power and for the future of energy in our state,” said Rick Anderson, senior vice president and senior production officer for Georgia Power. “By pairing battery storage with solar generation, we’re creating a more flexible and resilient grid that can respond to customer needs during periods of peak demand while supporting Georgia’s continued growth. Projects like this demonstrate how we are thoughtfully investing in innovative technologies and working alongside strong community and industry partners to deliver reliable, affordable energy for decades to come.”

At the 128 MW Robins Solar and Battery Facility, battery energy storage captures renewable energy during periods of lower customer demand and stores it for use when demand is higher, such as on cold winter mornings or during peak energy use. By pairing solar generation with battery storage, the facility provides greater flexibility and reliability while supporting Georgia’s growing energy needs.

The project is part of Georgia Power’s broader strategy to add cost-effective energy resources through the Georgia Public Service Commission’s (PSC) Integrated Resource Plan (IRP) process. Burns & McDonnell served as the engineering, procurement and construction contractor for the Robins Battery Facility and delivered the project on schedule.

Expanding Battery Storage Across Georgia  
The Robins Battery Facility is one of four battery energy storage projects approved in the 2023 IRP Update. Georgia Power has completed battery storage facilities in Cherokee and Lowndes counties totaling 579.5 MW and is nearing completion of a 57.5 MW facility in Floyd County.

The PSC has also approved nine additional BESS facilities across eight sites statewide, adding more than 3,000 MW of energy storage capacity. Sites were selected based on their ability to efficiently support grid operations, including proximity to existing infrastructure, substations and company-owned properties. Planned facilities include locations at Plants Bowen, Hammond, McIntosh, Wansley and Yates, as well as stand-alone sites in Hall and McDuffie counties.

To help meet growing energy needs, Georgia Power has also received approval for two solar facilities paired with battery storage, providing a combined 350 MW of generating capacity. These projects are designed to maximize solar production while minimizing land impacts. The new solar-plus-storage facilities will be located in Laurens and Mitchell counties.
